Primary bone tumors: percutaneous needle biopsy. Radiologic-pathologic study of 222 biopsies.

摘要: Findings of 222 needle biopsies were evaluated to determine the accuracy procedure in diagnosis, role biopsy limb-salvage procedures, contribution assessment tumor effect patients receiving chemotherapy or radiotherapy, and reasons for failure obtain diagnostic tissue. The overall diagnosis benign malignant tumors was 78.6%. major categories included osteosarcoma (50 patients), giant-cell (33 Ewing sarcoma (22 spindle-cell (15 patients). these 78%, 88%, 95%, 87%, respectively. results follow-up encouraging, with roughly a 70% adequacy who had 50% sarcoma. reason tissue 17 35 presence blastic tumors. cystic lesions faulty technique other failure. Percutaneous have primary bone is helpful tool, forms an important part procedure, contributes effects radiotherapy. To minimize obtaining adequate specimens should be obtained from their soft components, lytic areas, least dense while smear aspirate prepared cytologic examination clot embedded paraffin histologic study.
